The VALUE COLLECTION C703174 is a Grade 8 steel hex head cap screw designed for high-strength fastening applications in mechanical, structural, and industrial assemblies. With a 7/16-14 UNC thread and a 3.5-inch length under head, this partially threaded fastener delivers the clamping force required in demanding environments where standard Grade 5 hardware is insufficient. The uncoated finish makes it ready for field use, painting, or coating at the installer's discretion. It conforms to ASME B18.2.1, the governing standard for inch-series hex cap screws, ensuring dimensional consistency across the product run.
This screw is suited for use in fabrication shops, maintenance and repair operations, equipment assembly, and general industrial construction. Partially threaded geometry provides a smooth shank section that resists shear loading and allows accurate clamping on bolted joints where thread engagement is confined to the nut or tapped hole. It is appropriate for use by millwrights, pipefitters, ironworkers, and maintenance technicians working with steel-to-steel or steel-to-structural connections requiring Grade 8 tensile strength.
Designed as a standard inch-series hex head cap screw for any application requiring a 7/16-14 UNC Grade 8 fastener with a 3.5-inch length under head per ASME B18.2.1.
Installation should be performed by a qualified tradesperson using a calibrated torque wrench to achieve the proper clamp load for Grade 8 fasteners. Always confirm the mating nut or tapped hole carries a compatible Grade 8 or higher rating before assembly. Inspect threads for damage before installation and do not use an impact driver without torque verification. Follow applicable codes and engineering specifications for the assembly.
